Latest Air force data has the pressure to 974.3 mb.
 
Feels like -- from the recon reports we're seeing tonight -- that we may see a substantial jump with the 11 p.m. ET advisory, going from mid Category 1 to mid-to-high Category 2.

--30--
 
I think that now he has lost its convective "tail" it should allow for its overall structure to improve and really start to strengthen and recon is showing that

...HURRICANE HUNTER AIRCRAFT FIND A STRENGTHENING DORIAN...


SUMMARY OF 1100 PM AST...0300 UTC...INFORMATION
-----------------------------------------------
LOCATION...23.3N 68.4W
ABOUT 295 MI...470 KM ENE OF THE SOUTHEASTERN BAHAMAS
ABOUT 580 MI...930 KM E OF THE NORTHWESTERN BAHAMAS
MAXIMUM SUSTAINED WINDS...105 MPH...165 KM/H
PRESENT MOVEMENT...NW OR 325 DEGREES AT 12 MPH...19 KM/H
MINIMUM CENTRAL PRESSURE...977 MB...28.85 INCHES


WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.

Interests in the northwestern and central Bahamas should monitor the
progress of Dorian. Watches may be required for portions of this
area on Friday.


DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Hurricane Dorian was
located near latitude 23.3 North, longitude 68.4 West. Dorian is
moving toward the northwest near 12 mph (19 km/h), and this general
motion is expected to continue through Friday. A west-northwestward
to westward motion is forecast to begin by Friday night and continue
into the weekend. On this track, Dorian should move over the
Atlantic well east of the southeastern and central Bahamas tonight
and on Friday, approach the northwestern Bahamas Saturday, and move
near or over portions of the northwest Bahamas on Sunday.

Maximum sustained winds have increased to near 105 mph (165 km/h)
with higher gusts. Dorian is expected to become a major hurricane
on Friday and remain an extremely dangerous hurricane through the
weekend.

Hurricane-force winds extend outward up to 25 miles (35 km) from the
center, and tropical-storm-force winds extend outward up to 105
miles (165 km).

The latest minimum central pressure estimated from Hurricane Hunter
data is 977 mb (28.85 inches).
